ESET Business Edition (version 184.108.40.206) was recently installed on my laptop (Windows 7 Ultimate 64bit). Since the installation I have frequently gotten various BSoD errors. One BSoD indicated a problem in fastfat.sys another one said page fault in non-paged area. This seems to happen frequently when I mount TrueCrypt volumes (version 7.0). I have formatted my flash drive and created a new TrueCrypt volume to see if the errors were there. My first attempt to mount a fresh TrueCrypt volume created another BSoD.
